I've a Hyperpen 4000.. which worked charmingly some time ago (I was with mint 6). After sometime I've decided to pass to mint 7, and then, install again my tablet... but things seem didn't get right now. The way I've always used to (successfully) install my pen drive was:1. Install a deb package (xserver-xorg-input-hyperpen_1.2.0-1build1_i386.deb)2. some xorg.conf mod... the mod is:

Xorg.conf is really not used anymore, only for settings added to it.This means it will try to load anything it finds.You will have to remove xserver-xorg-input-hyperpen so it's not loaded.You should be looking at the logs to make sure that it's the problem though.
